In this book, we will explain how to convert a PDF file to a fixed layout ePub version 3 file. This is possible since the version 3 of the ePub format which includes now the fixed layout mode in addition to the traditional flowing text mode. We will use free open source tools, mainly pdf2htmlEX, with an example under Linux.Update (2021): see https://github.com/dodeeric/pdf2epubEX to use a script which makes the conversion automatically.
